Switch Business Rates Consultant During Appeal (2026)

Switching business rates consultants mid-appeal is allowed at every stage of the process, and it happens more often than most ratepayers expect in 2026. Yes, you can switch business rates consultants during an appeal – the case itself doesn't belong to the agent, it belongs to you as the ratepayer, so a new consultant can pick it up at Check, Challenge or Appeal stage. However, you will normally be in a contract with a company so beware of trying to switch agents before checking that will still be liable for fees under your original contract. If you do speak to another agent they should warn you about this before taking your instruction – if they do not then be very cautious about working with them.

Why this matters

A business rates appeal can run for well over a year once you count the Check, Challenge and Appeal stages together. If your consultant goes quiet, misses the evidence window, or simply isn't specialised in your property type, that delay costs you money – every month the case drags on is another month you're paying the wrong rateable value. Knowing you can track your case status and switch agents without losing your place in the queue changes how much leverage you have over a slow or unresponsive firm.

Can you switch business rates consultants during an appeal?

Switching is a paperwork exercise, not a legal barrier. Here's what actually happens:

1. Review your current agreement. Check for exit clauses, notice periods, or success fees tied to work already submitted.
2. Notify your existing agent in writing. This creates a record and starts any notice period their contract requires.
3. Revoke and re-authorise on the VOA portal. The Valuation Office Agency only acts on instructions from the currently authorised agent, so you (or your new consultant) must formally replace the old authorisation.
4. Hand over the case file. Your new consultant needs copies of everything submitted so far – evidence, correspondence, and the current Check or Challenge reference.
5. Continue from the existing stage. The case doesn't reset. If you're four months into an 18-month Challenge decision window, that clock keeps running regardless of who's representing you.

Those windows are set by the Check, Challenge, Appeal (CCA) framework the VOA runs in England, and they apply no matter which agent's name is on the file. A new consultant inherits the clock, not a fresh one.

Switching during the Check stage

This is the easiest point to switch. Little formal evidence has usually been filed, so a new consultant can review your property details, correct any factual errors on the VOA's record, and refile with minimal loss of momentum.

Switching during the Challenge stage

This is where handover quality matters most. The 4-month window to submit a Challenge after a Check decision is tight, and if your previous consultant already lodged evidence, your new agent needs that evidence in full before adding anything further. A poor handover here is the single biggest reason switching mid-Challenge goes wrong.

Switching during the Appeal (tribunal) stage

Once a case reaches the Valuation Tribunal for England, switching still works, but your new representative needs the full bundle: the original Check, the Challenge decision notice, and any correspondence with the VOA. Tribunal deadlines don't pause for a change of agent.

Why ratepayers switch business rates consultants mid-appeal

• No updates for weeks or months – you can't get a straight answer on where the case stands.
• Missed evidence deadlines inside the Challenge or Appeal window.
• Generalist agents handling specialist property types – a warehouse, care home or holiday park valuation needs different evidence to a high street shop.
• Fee disputes – unclear no-win-no-fee terms or unexpected charges.
• Firm closure or loss of accreditation – RICS or IRRV membership lapsing mid-case.
• Better sector fit elsewhere – some firms specialise in retail or hospitality valuations and simply build stronger comparable evidence for those sectors.

The verdict: you keep full control over who represents your case at every stage, but a bad handover costs you more time than a slow original consultant ever would.

Do I have to pay my old consultant if I switch?

It depends on the contract you signed, not on the fact that you switched. Fixed-fee agreements may charge for work completed; no-win-no-fee agreements typically only pay out on a successful reduction, but the wording on what counts as "completed work" varies firm to firm, so read the small print before you commit to a new consultant.

Will switching consultants delay my appeal?

Switching itself doesn't delay anything with the VOA – the statutory 4-month and 18-month windows keep running regardless. The delay risk comes entirely from a slow or incomplete handover between your old and new consultant.

Can I appoint two consultants at once?

1. The VOA portal only recognises one authorised agent per case at a time, so appointing a second consultant automatically means revoking the first one's access.

Appeal My Rates UK, as a firm of RICS and IRRV-aligned rating surveyors covering Wales and England, reviews existing Check or Challenge submissions at no obligation before taking over a case, so you can see exactly what's been filed and what's missing before you decide to switch. Comparing how different firms handle a takeover is also worth doing side by side – see how Appeal My Rates UK compares against Knight Frank on case handling before you commit.

FAQ

One last thing

Most ratepayers don't realise the old agent keeps portal visibility on the case until you actively revoke their authorisation – simply signing with a new consultant doesn't remove the previous one automatically. If you're mid-Challenge and want a clean handover, revoke the old authorisation the same day you appoint the new agent, not after.But again, beware of contract clauses and ensure you check before switching.
